Tree Trimming for Line Clearance

Trees too close to power lines can become a hazard and contribute to power outages. Tree limbs and other vegetation falling on overhead utility lines during storms are among the most common causes of power outages. Removing potentially dangerous tree limbs and other vegetation helps Hamilton Utilities improve reliability of service, increase the safety of crews and customers, and is mandated by Ohio and Federal law.

The Department of Infrastructure and contracted professionals consider a number of factors when evaluating trees/vegetation for trimming, including condition, species, growth rate, power line voltage, and proximity to power lines. Crews use pruning techniques that were developed by the National Arborist Association and are accepted as industry standards by the American National Standards Institute (ANSI), the Natioanl Arbor Day Foundation, and the International Society of Arboriculture.

The City of Hamilton Electric System includes approximately 250 miles of overhead transmission and distribution lines. As part of routine maintenance, trees and other vegetation within 40 feet on either side of transmission lines and within 20 feet on either side of distribution lines are trimmed and/or removed. On average, 50 miles of lines are inspected and trimmed annually to ensure the entire electric system is cleared every 5 years. If an area requires tree/vegetation trimming and/or removal, property owners will be contacted via mail and provided a timeframe for when work will be completed on their property.

Tree trimming crews will chip debris (less than 4 inches in diameter) created by normal trimming activity. Logs greater than 4 inches in diameter will be cut to handling length and left for the property owner’s use.

In the case of emergency situations when there is an immediate safety hazard, loss of power threat, or loss of power, trees and other vegetation may be removed without prior notice to property owners. Crews do not clean-up or remove branches and debris that occur during storm restoration work.
